Terrible Hours, Terrible Management, Terrible Work-life Balance
Run, don't walk, from this company. If you decide not to follow that advice, be prepared to work all hours of the day with rotating shifts, daily. Your managers don't communicate, so you never really know what is going on. Also, you will be certified by the FRA, but the way Denver Transit Operates you will always be in fear of being decertified and being off work, unpaid.
Denver Transit Operators doesn't seem to understand how to operate a transportation company. Their turnover is sky-high, but they don't seem to do a thing about it. When the Gold Line opened (G-Line) they literally had to use Transportation Supervisors to run the lines because they were so short-handed.
The pay is not commensurate for the responsibility you bear. These are heavy rail commuter trains and yet light rail operators make as much or more per hour. Do yourself a favor and apply to RTD directly. You'll earn more money, more time off, and a pension.
